Correct Answer: Intracellular transport

Explanation:

A cytoskeleton is the frame that gives shape to a cell. And also it offers support, and facilitates movement through three main components:

microfilaments,

intermediate filaments, and

microtubules.

 

The cytoskeleton helps the cell move in its environment and controls the movement of all of the cell's interior workings.

Correct Answer: Tuber

Explanation:

Tuber is considered as a modified stem. These type of stems carry out special functions that are important for the plant to survive. Tubers serves as a food reserve and bearing buds wherein new plants can grow.

Correct Answer: Decomposers are those organisms that recycle matter in the ecosystem..

Explanation:

Decomposers are organisms that break down dead or decaying organisms, and in doing so, they carry out the natural process of decomposition.

 

The statement "Decomposers are those organisms that recycle matter in the ecosystem" describes decomposers.

Correct Answer: Nucleus

Explanation:

In all plants and animal cells chromosomes are located in the Nucleus of the cells.

 

 

 

The Chromosomes are thread like structures present in the nucleus of the cells which are made up of proteins and a single molecule of DNA.

 

 

 

Their function is to carry the characteristic features of parent cells to daughter cells. 

Correct Answer: DNA

Explanation:

The inherited traits of an organism are controlled by DNA molecules.

 

The traits an organism displays are ultimately determined by the genes it inherited from its parents, in other words by its genotype. Animals have two copies of all their chromosomes, one from each parent.

 

Correct Answer: blood

Explanation:

In human body, glucose is stored in blood stream before it is converted to glycogen. Excess glucose is stored in the form of fats. After conversion, glycogen is stored in Muscles and Liver.

Correct Answer: All the above

Explanation:

Random mutations are the ultimate source of genetic variation. Mutations are likely to be rare and most mutations are neutral or deleterious, but in some instances, the new alleles can be favored by natural selection. Polyploidy is an example of chromosomal mutation.

 

Mutations are changes in the DNA. A single mutation can have a large effect.

1) mutation - an alteration in DNA sequence, various types

2) intragenic recombination - results in entirely new associations of genes not present in either parental genome.

Two forms of intragenic recombination:

a) crossing over
b) independent assortment
3) reticulation ? acquisition of genetic material from unrelated or relatively unrelated sources (e.g., hybrid species, horizontal gene transfer).

Correct Answer: Bacteria take DNA from their environment.

Explanation:

"Bacteria take DNA from their environment" is what best describes transformation in bacteria.

Correct Answer: Aldosterone increases sodium reabsorption by increasing the number of Na+-K+ ATPase pumps in the luminal membrane of the proximal tubule.

Explanation:

Aldosterone, the main mineralocorticoid hormone, is a steroid hormone produced by the zona glomerulosa of the adrenal cortex in the adrenal gland. It is essential for sodium conservation in the kidney, salivary glands, sweat glands and colon.

Correct Answer: All the above

Explanation:

The central nervous system CNS is responsible for integrating sensory information and responding accordingly.

It consists of two main components::

 1. The brain

 2. The spinal cord

The brain is the center of our thoughts, the interpreter of our external environment, and the origin of control over body movement. The brain can be divided into four main lobes: temporal, parietal, occipital and frontal.

 

The spinal cord serves as a conduit for signals between the brain and the rest of the body.
